HAY-BURNER.

SPECIFICATION forming part of Letters Patent No. 371,332, dated October 11, 1887.

Application filed March 28, 1887. Serial No. 232,721. (No model.)

T0 aZZ whom it may concern:

Be it known that I, GODFRIED LAUBE, a citizen of the United States, and a resident of Huron, in the county of Beadle and Territory of Dakota, have invented certain new and useful Improvements in Hay-Burners; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, referen ce being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a perspective View of my improved hay-burner, showing the same secured in its operative position upon a cook-stove of ordinary construction. Fig. 2 is a central longitudinal vertical sectional view of the same. Fig. 3 is a perspective view of the attachment, with its center piece and lids and also with the magazine or cylinder removed. Fig. 4 is a perspective detail view of the magazine or cylinder partly broken away to show the construction and arrangement of the gas-tube; and Fig. 5 is a vertical transverse sectional view taken on the plane indicated by line 00 00, Fig. 2.

The same letters of reference indicate corresponding parts in all the figures.

My invention consists in an improved hayburner, which is adapted to be attached to any ordinary cook-stove, and which will evenly consume the hay without allowing any smoke or gas to escape into the room, and which will obtain the maximum of heat from the quantity of hay'consumed; and my invention will be hereinafter fully described and claimed.

Referring to the several parts by letter, A indicates a cook-stove of ordinary construction, to which my improved hay-burner is shown attached inoperative position.

B indicates the sheet-iron body of my improved attachment, the top of which is wholly of cast-iron, and this attachment is secured upon the top of the stove A, after the center piece and lids of the stove have been removed, by means of the clamps O O and screws D D, the forward lower part of the body B being likewise formed with the downwardly-bent lip B, which assists, as clearly shown in the sectional view, Fig. 2, of the drawings, in holding the attachment firmly in position on the stove A. This body B extends entirely over the top of the stove and extends considerably in advance of the same at its forward end, as shown, that part of the top and bottom of the attachment which extends over and coincides with the top opening of the stove proper being open, as shown, this top opening, B of the attachment being covered by the removable center piece, E, and the lids E E, the large communication between the interior of the stove and the main part of the body B giving room for a full and complete combustion, and also forming a large heating-drum, as it were. The large space thus left clear on the top of the attachment gives a large clear surface for cooking, that part of the attachment being provided, as before described, with removable plates or lids E" and the removable center piece, E, similar to those of the stove proper.

The side piece, B", of the body B is formed of a piece or strip of sheet-iron, and the front of this strip is formed with the draft-openings F and the draft-slide F, for regulating the draft through the said openings. The forward end of the body B extends, as shown, in advance of the front of the stove-top, and the bottom of this extended portion is formed with a series of slots, G, forming a grate through which the ashes of the burned hay fall into an ash-pan,H, which rests in a casing, I, immediately beneath the said slots, and which is removed by opening the hinged door J at one end of the said casing, the said ash-pan H having at one end a handle, H, and being provided with a pivoted bail, H by which it can be convenientiy carried and which can be folded in out of the way when the pan is to he slid into the casing I.

The upper side of the forward extension of the body B above the series of slots G is formed with a circular opening, K, having preferably an upwardlyextending rim -fiange, k, on the forward part. Nearly one-half of this opening is provided with a solid metallic bottom, L, while across the open space, between the straight rear edge of this bottom plate, L, and the rear part of this opening K, are arranged the three grate-bars M, which are bent downward, as shown, immediately above the series of slots G; but thelower portion of these gratebars is some distance above the said slotted bottom of the body B, so as to leave an open IOC space between the said slotted bottom and the hay or straw supported by the grate-bars M,so

as not to shut oil the circulation of air, thus' is made in the form of a cylinder with a closed top, the lower open end of the cylinder being provided with a cast-iron flanged ring, 0, and the lower end of the magazine fits within the upwardly-extending rim-flange k of the opening K, the outwardly extending flange of the ring 0 bearing upon the upper edge of the flange k; and it will be seen that by this arrangement the magazine can be readily rotated, for the purpose hereinafter specified, with very little friction. This cylinder is provided on opposite sides, for convenience in handling it, with the handles P, each handle being formed of two strips of metal,l? P',which arecrossed at their centers at an angle in about the shape of the letter X,and have their ends riveted to the sides of the cylinder, as

shown; and it will be seen that by this eonstruction the handles are rendered exceptionally strong, resisting pressurein all directions both up and down and to either side.

metallic strip Q,Whl0h is secured (riveted) by its edges to the inner side of the cylinder, extending from the-topto the bottom of the same and swelling out toward its center, as clearly shown in the detail view, Fig. 4, so as to leave a longitudinal space between it and the side of the cylinder to which its edgefianges are secured, and the central part of this strip or tube Q (for I shall denominate it a tube, as, in conjunction with the side of the cylinder to which itiis secured, it forms a tubular space) is formed with a series of transverse apertures, Q, leading from the inside of this tube to the interior space of the magazine, for the purpose hereinafter specified.

In operation, when the bodyB has been secured in operative position upon a stove A, the center piece, E, and the lids E having been placed in position, or any one of them removed, and a utensil placed in the opening thus uncovered to heat, the hay or straw is placed in the magazine N, and the cover a, which is used to close the openingK when the magazine is not in position, having been removed, the magazine is placed in position on the body B with its lower end edge fitting within the flangekof the opening K,the lower part of the straw or hay resting upon and being supported by the solid half-bottom L and the three grate-wires M, and, the draft-slide having been opened to the desired extent,the hay is lighted through the small door b in the side B It will be seen that as the lower portions of the downwardly-bent grate-bars M do not extend down to the slots G the draft will not be interfered with, a clear space'being thus provided for the circulation of the air, as will be readily seen. The solid front bottom, L, will protect the forward lower part of the hay or straw from burning, while the rear lower part thereof, which rests in the downwardlybent grate -bars M, will burn steadily, and when this back part of the contents of the magazine has been burned out to a certain height the cylinder is turned for a half-circle, which can be readily and conveniently done by taking hold of the handles 1? until the unburned lowerpart of the hay or straw comes over the gratebars, when the contents of the magazine will again settle down in the gratebars as it is gradually burned,until theformer burned-out portion, or'rather the bottom of what was the rearburned-out portion, strikes the bottom plate, L, and whenever the rear part of the cylinder contents is burned out to a certain height the magazine is given a half-' inner edge, and the lower open end of the per- Within the cylinder, to the interior side of 1 'one side thereof, is secured the longitudinal l 'tube comes to the front; or when the cylinder is given a half-turn again the lower end of the tube is over the grate-bars M, and the efiect of this construction and arrangement is that all gas that will accumulate in the cylinder or magazine will pass through the perforations Q into the tube Q, and then down to the fire, so as to be consumed by the same, passing directly through the spaces between the gratebars M when the tube is at the back and through the recess L of the bottom L when the tube is turned with the cylinder to the forward side.

The ashes of the burned hay or straw fall through between the grate-bars M and through the slots G down into the ash-pan H, and this use, the opening K may be closed by the cover n, and fire can then be built in the stove in the usual manner.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my invention will be readily understood.

It will be seenjthat my improved burner for hay or straw is simple and strong in construction, and can be attached in a few moments to any ordinary cook-stove, and that it is exceedingly efficient in its operation. The hay or straw is evenly and steadily burned, and no smoke or gas is permitted to escape into the room, while the maximum of heat is obtained The stove can be used for cooking purposes while the body Bis attached upon it, either while the hay or straw is being burned or after the magazine-cylinder has been removed and an ordinary fire has been kindled in th stove-grate proper.

Having thus described my invention,what I claim, and desire to secure by Letters Patent of the United States, is
